Patented Nov. 1, 1932 PATENT OFFICE I OSCAR J. HORGER, 0F CANTON, OHIO, ASSIGNOR TO THE TIMKEN ROLLER BEARING COM- PANY, OF CANTON, OHIO, A CORPORATION OF OHIO JOURNAL BOX OONSTRUCTION- Application filed April 30,

My invention relates to railway car truck journal box constructions, particularly to those of dump cars adapted for use with rotary car dumps wherein the dump cars are inverted for unloading them. During this operation lubricant which normally resides in the bottom of the journal boxes, is thrown against the sides thereof with resultant leakage through the dust guard or enclosure rings; and the principal object of the present invention is to provide means for accommodating the lubricant in a journal box in an inverted position so as to prevent leakage of the lubricant therefrom.

My invention consists principally in providing a dump car journal box with upwardly extending hollow tubular members having their top ends closed and thei lower ends communicating with the lubricant reservoir portion of the journal box and which accommodate lubricant when the car is dumped. My invention further consists in the journal box construction and in the parts and combinations and arrangements of parts hereinafter described and claimed. In the accompanying drawings, which form part of this specification, and wherein like reference numerals refer to like parts wherever they occur,

Fig. 1 is a side view of one end of a dump car truck side frame equipped with a split journal box construction embodying my invention,

Fig. 2 is a sectional view along the line 2-2 in Fig. 1,

Fig. 3 is a detail side view of the removable lower portion of the journal box,

Fig. 4c is a detail plan view of the removable lower portion of the journal box,

Fig. 5 is an inner end view of the lower portion of the journal box,

Fig. 6 is a sectional View along 6-6 in Fig. 4,

Fig. 7 is a sectional view along the line the line 77 in Fig. 4, and

Fig. 8 is a sectional view along the line 8-8 in Fig. at.

In the construction illustrated in Fig. 1, a dump car truck side frame 1 has a depending upper journal box portion 2 integral with 1931. Serial no; 533,981.

its end; and the sidesof the upper journal box portion are provided along the lower edges with a series of outwardly projecting lugs 3, and a separate lower ournal box portion 4 having outwardly projecting lugs 5 along the sides of its upper edge, is secured to the upper journal box portion 2 by bolts 6 extending through holes 7 in the lugs 3 and 5 projecting from the upper and lower j ournal box portions, respectively. Obviously, the upper and lower journal box portions se cured together as described constitute a split journal box 8.

The outer end of the upper journal box portion is provided with an opening 9and with a closure cap 10 therefor, said closure cap 10 being secured in position by means of a clamp spring member 11 whose lower end is held by a loop 12 secured to the lower journal box portion. The top of the journal box is'provided at its outer end with a lug 13 of the kind commonly used for hingedly securing present standard closure caps to the journal box; so that hinged caps of the present type may be used, if desired. Said lug 13 supports the upper end of the closure cap 10 shown in the drawings. Obviously, any suitable means may be used for closing the opening, for instance, a panel may be cast over the frame opening instead of using a lid.

duced portion 14a of an axle 14; and interposed between the reduced portion lea and the journal box are roller bearings 15 held by suitable means. The inner end of the journal box is provided with two inwardly extending spaced annular flanges 16 defining an annular recess 17 between them; and mounted in said recess is a two piece inner closure ring and dust guard 18 which engages the outer periphery of the axle.

The lower portion of the journal box is provided with two oppositely disposed tubular members 19 which communicate with the inside of the lower portion of the journal box adjacent to its inner end and extend upwardly along the sides and partially beyond the inner end thereof and terminate at about the top of the journal box. These tubular Extending into the journal box 10 is remembers, which may be described as oil stand pipes, are located on the inner end of the journal box and are of such shape and crosssection near their top ends as to extend to the inside of the truck side frame 1.

The so-called stand pipes are of sufiicient size to accommodate the bearing lubricant when the journal boxes are turned substantially upside down in dumping the cars. Qbviously, the lubricant in the journal box instead of being held in the inverted top portion thereof, will flow into the tubular stand pipes and thus relieve the liquid pressure upon the dust guard or inner enclosure ring to prevent the lubricant from leaking therethrough.

.Wlnle I have shown and described a split journal, box having two oppositely disposed stand pipes communicating therewith, it is itkobvious that, without departing from my invention, any number of standpipes of any size and shape may be used with any type of journal box,'whether split or integral. Furthermore, instead of locating the standpipes near the inner end of the box it may be practicable to have them communicate with other portions of the box; and accordingly, I do not wish to limit my invention to the precise construction shown and described.

What I claim is: V

1. A dump car journal box having a hollow stand pipe communicating with the inside lower portion thereof adjacent to its inner end, said stand pipe extending upwardlyalong the side oi said journal box and partially beyond the inner end thereof. 7

, 2. A dump car journal box having two oppositely disposed stand pipes communicating with the inside lower portion of said journal box adjacent to its inner end, each of said stand pipes extending upwardly along the respective sides of the journal box and partially beyond its inner end.

3. Adump car journal box comprising an upper portion and a removal lower portion having an upwardly extending pipe having its upper end closed and having its lower end opening into said lower portion for accommedating lubricant when the car is dumped.

4. .A dump car truck construction comprising a side frame member having an integral upper journal box portion extending downwardly from its end, a removable lower j our- {2111 box portion cooperating with said upper journal hox portion, said lower journal box portion having a hollow stand pipe communicating with the inside of said journal box and extending upwardly along the side of said upper journal box portion and on the inner side of said side frame member for accommodatinglubricant when the car is dumped.

5. The combination of a dump car journal box having a removable lower portion, an axle extending therein and roller bearings interposed between said journal box and said axle, the removable lower portion of said journal box having a hollow stand pipe communicating therewith for accommodating the bearing lubricant when the car is 70 dumped.
